• Save — The oscilloscope saves the screen image when an error is detected. In
the Save menu (press [Save/Recall] > Save ), select an image format (*.bmp or
*.png), destination (on a USB storage device), and file name (which can be
auto-incrementing). If errors occur too frequently and the oscilloscope
spends all its time saving images, press the [Stop] key to stop acquisitions.
• Print — The oscilloscope prints the screen image when an error is detected.
This option is only available when a printer is connected as described in "To
print the oscilloscope's display" on page 227.
• Measure — Measurements (and measurement statistics if your oscilloscope
supports them) run only on waveforms that contain a mask violation.
Measurements are not affected by passing waveforms. This mode is not
available when the acquisition mode is set to Averaging.
Note that you can choose to Print or Save , but you cannot select both at the
same time. All other actions may be selected at the same time. For example,
you can select both Stop and Measure to cause the oscilloscope to measure and
stop on the first error..
On G-suffix oscilloscope models (that have a built-in waveform generator), you
can output a signal on the front panel Gen Out connector when there is a mask
test failure. See "Setting the Gen Out Source" on page 240.
• Source Lock — When you turn on Source Lock using the Source Lock softkey, the
mask is redrawn to match the source whenever you move the waveform. For
example, if you change the horizontal timebase or the vertical gain the mask is
redrawn with the new settings.
When you turn off Source Lock, the mask is not redrawn when horizontal or
vertical settings are changed.
• Source — If you change the Source channel, the mask is not erased. It is
re-scaled to the vertical gain and offset settings of the channel to which it is
assigned. To create a new mask for the selected source channel, go back up in
the menu hierarchy; then, press Automask , and press Create Mask .
The Source softkey in the Mask Setup menu is the same as the Source softkey
in the Automask menu.
• Test All — When enabled, all displayed analog channels are included in the
mask test. When disabled, just the selected source channel is included in the
test.
